Description of the walk

The hike begins at the car park in front of the main gate of the Domaine de Rentilly, Route de Guermantes (D217b) in Bussy-Saint-Martin.

(S/E) Enter the park and, after studying the map to familiarise yourself with the layout of the different areas, turn left onto the path towards the Grille de la Brosse. It runs roughly parallel to the Route de Guermantes.

(1) At the Grille de la Brosse, turn right towards the château (a square post bears directions).

(2) Go around the castle, passing in front of the main façade, then follow the ponds until you reach the third lane.

(3) Turn right and go down a few steps. Continue and turn right at the next intersection, then left into the lane at the corner of a grassy retention pond. Two hundred metres further on, turn right and continue towards the Grille des Gardes.

(4) Turn left into the lane closest to the one you have just left. It goes back up into the woods. Follow it to the park fence, where it turns left into a rectangular clearing.
Take the first lane on your right. It ends at the lane surrounding the French garden. Turn right and, after going about a quarter of the way around the statue, turn right onto the path that leads to the park's Black Gate.

(5) Leave the park. Cross the moat bridge, turn left at the Rond-Point de la Grille Noire, cross Rue de l'Etang and, a few metres further on, turn left onto the path leading to the Vallée de la Brosse (signpost). After a left turn near a white metal cross, this road arrives at the edge of a housing estate. Continue along Chemin de la Croix Blanche.

(6) After passing through the gate, turn right onto Chemin de l'Etang de la Broce (see sign on the post).
At the roundabout, take the wide tree-lined lane closed off by low walls forming chicanes. Follow the path on the right; it curves to the right.

(7) Pass along the Etang de la Broce. When the path reaches a junction with several paths, continue in the centre on the widest one, which climbs the slope towards industrial buildings whose roofs are visible. You will reach a car park near the RER railway line.

(8) Turn left onto the path that starts with a footbridge and heads towards the Etang de la Broce (signpost).
This path descends. At the next crossroads, continue towards the Etang de la Loy (signpost) and continue downhill. The path winds along the Ru de la Brosse, which you cross on a bridge on your right. Then take the path immediately on your left and cross the stream again a little further on the left.

Continue to the D217b. Cross the road and continue opposite towards the Etang de la Loy, using the path for horse riders. When you reach a fork where a signpost indicates right for horse riders and left for cyclists, take the path for horse riders to get closer to the bank of the Etang de la Loy.

(9) At the crossroads, take the path on the left that crosses the dam. This will take you to the edge of a housing estate where a signpost at the first crossroads indicates the direction of the Parc Culturel de Rentilly. Do not turn, but continue straight ahead until you reach a very large tree-lined avenue, which you take on the left (a signpost also indicates the direction of the Parc Culturel de Rentilly).

(10) Continue. At the end of this lane is the car park (S/E).

From Rentilly Park to Vallon de la Brosse - VISORANDO
between 6 and 7... road blocked and impossible to pass further on... mountain of earth
it seems we are being forced to use the new cycle path
The farmer does not seem to agree with us using the path
so your route needs to be changed

It was my first hike and it was a real pleasure! The route was very easy to follow with the app. Very pleasant to do in autumn and perfectly suited to beginners.

This trail is a wonderful discovery. It starts in the Parc de Rentilly, which is great, and then winds its way through the countryside, where it's all footpaths and very easy to drive on, with no serious gradients.
Highly recommend it.

The walk is really nice, with different types of landscape including woods, fields and parkland. Very quiet, few roads and not very busy.
However, the parish specific to Brittany was very muddy and sometimes even difficult to walk without getting stuck in the mud...
Otherwise top class!

There were 3 of us to get our bearings with the information, the map and plan didn't always seem to match up, so we had a few problems.

A wonderful discovery, both for the park and its magnificent trees and for the trail that follows. The route was very well explained and simple, with no difficulties and very clean, with passages through villages, countryside, woods and streams.... A great family hike, I highly recommend it at any time of year, with all the different landscapes to feast your eyes on...

We really enjoyed this pretty walk with its varied scenery: heritage, landscaped parkland, countryside, undergrowth, ponds and a pretty stream. The path is easy and accessible to all.

This is a great walk that I'm doing for the second time. Magnificent route, very well signposted and laid out. Superb stretches of water, lots of birds, rural vegetation. Really enjoyable. Picnic in the park on the way back. What a beautiful place!

Thank you for this route, which we've extended a little with the 2 villages of St Martin and St Georges. Beautiful parkland at the start, but some roadworks made it difficult to take photos. Lovely day and thank you to the creator of the walk.

A really pleasant and varied walk, with sections through undergrowth and alongside ponds. The autumn colours are magnificent.
I joined the circuit from Torcy station and point 5, so I got a bit lost on the passage between points 5 and 6.
In any case, do it again...
